So I bought the CT-2 device. I installed the Windows software on my PC. First thing I did was install the driver by selecting "Driver" -> "Install_Driver". I plug in the CT-2 device to a USB port, but it just says "No port available".
I tried the same sequence on another Windows machine, with the same result.
The CT-2 does power up and shows the USB voltages and amperages. But I am unable to get the Windows PC app to connect to the CT-2 device.
I guess there was something wrong with the cable. I just tried a different cable and now it is working. Strange because the other cable works with another USB device... so I don't know really. Thanks for the help!
